The round base of a copper tea kettle has a diameter of 18 centimeters. What is the base's circumference?

Respuesta :

Answer:

C = 18 pi cm or approximately 56.52 cm

Step-by-step explanation:

The circumference of a circle is given by

C =  pi * d

We know the diameter is 18 cm

C = pi * d = 18 pi cm

If we approximate pi by 3.14

C = 3.14 * 18

C is approximately 56.52 cm
